> startup used too much time to load edits

> Key: HDFS-7609
> URL: https://issues.apache.org/jira/browse/HDFS-7609
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 2.2.0
> Reporter: Carrey Zhan
> Assignee: Ming Ma
> Labels: BB2015-05-RFC
> Attachments: HDFS-7609-2.patch,
> HDFS-7609-CreateEditsLogWithRPCIDs.patch, HDFS-7609.patch,
> recovery_do_not_use_retrycache.patch
>
>
> One day my namenode crashed because of two journal node timed out at the same
> time under very high load, leaving behind about 100 million transactions in
> edits log.(I still have no idea why they were not rolled into fsimage.)
> I tryed to restart namenode, but it showed that almost 20 hours would be
> needed before finish, and it was loading fsedits most of the time. I also
> tryed to restart namenode in recover mode, the loading speed had no different.
> I looked into the stack trace, judged that it is caused by the retry cache.
> So I set dfs.namenode.enable.retrycache to false, the restart process
> finished in half an hour.
> I think the retry cached is useless during startup, at least during recover
> process.
